Summary: During salinity stress, Mozambique tilapia adjust glucose homeostasis by increasing glucose content and Na+ -K+ -ATPase activity in gill and intestine, while decreasing liver and gill glycogen content. Upregulation of GLUTs in these tissues suggests higher glucose influx into cells for catabolism, maintaining glucose homeostasis during salinity acclimation.

Summary: The Mozambique tilapia Oreochromis mossambicus is an important aquaculture species that is vulnerable and listed on the IUCN Red List. A preliminary survey conducted in 2011 examined 30 Mozambique tilapia from Lake Urema in Gorongosa National Park and found two species of copepods and a monogenean as ectoparasites, and one trematode and one nematode as endoparasites. This study provides new parasite records for O. mossambicus in Mozambique and establishes a baseline for monitoring the presence of ichthyoparasites associated with the introduction of non-native fish species.

Summary: This study investigated the effect of aquacultural stressors on the pituitary-testis axis in a breeding cichlid fish. The results showed that exposure to stressors led to a decrease in spermatid production, suppression of LH synthesis, and decreased androgen receptor expression in the testis. The findings suggest that chronic aquacultural stressors can disrupt the reproductive process in fish.

Summary: In this study, we performed genome sequencing and re-sequencing of Mozambique tilapia and identified the sex chromosome and sex determining region. We developed three sex-linked markers to identify different sex genotypes in Mozambique tilapia. This study lays a foundation for the establishment of marker-assisted selection and sex-controlled breeding techniques, as well as for the identification of the sex determining gene in Mozambique tilapia.

Summary: This study experimentally challenged Mozambique tilapia with a virulent strain of TiLV and found that high concentration TiLV caused skin issues, enteritis, and a mortality rate of 77.78% in this fish species. Severe histopathological changes were observed in the infected fish, confirming the susceptibility of Mozambique tilapia to TiLV infection.

Summary: The Mozambique tilapia is an important food fish with males preferred in aquaculture due to their faster growth. Studies have identified XY and ZW sex determination systems in the genome, with shared sex determining regions narrowing down to specific genes. The annotated genome assembly provides valuable insights into the genetic sex determination in tilapias.

Summary: This study showed that salinity stress can impair gill structure and reduce the antioxidant capacity of Mozambique tilapia. The synthesis of myo-inositol and changes in carbohydrate metabolism may be effective strategies to alleviate the adverse effects of salinity stress on fish.

Summary: The use of pesticides in agriculture can harm the surrounding environment, including aquatic systems. In many regions, the impact of pesticide pollution on key aquatic species has not been well-researched. This study examined the behavioral responses of the Mozambique tilapia fish after exposure to commonly used macadamia pesticides. The results indicated harmful effects, such as erratic swimming and mortality, and provided lethal dose values for the tested pesticides.

Summary: The disrupted behavior and respiratory distress effects of acute deltamethrin exposures were investigated in adult Mozambique tilapia. The study found that deltamethrin concentrations were associated with toxicological responses, leading to behavioral abnormalities and impaired respiratory function. The findings suggest neurotoxicity and respiratory distress as potential mechanisms underlying the observed effects in fish.

Summary: The study identified specific amino acid and peptide transporters in the kidney of Mozambique tilapia, which play important roles in osmoregulation and nutritional status of fish. Transporters expression was influenced by salinity and feeding time, indicating interaction between these factors. Immunofluorescence staining showed distinct localization of transporters in different segments of nephrons.

Summary: In this study, the effects of cortisol on the regulation of glycogen metabolism biomarkers in the gills of tilapia were investigated. It was found that cortisol regulated glycogen metabolism by promoting the expression of glycogen phosphorylase mRNA in the gills. These findings suggest that cortisol directly acts on glycogen-rich cells in the gills and regulates glycogen metabolism.

Summary: This study assessed the potential of Crocodylus niloticus meat meal as a replacement for fishmeal in Oreochromis mossambicus diets. The results showed that there were no significant differences in weight gain, growth rates, feed conversion ratios, or protein efficiency ratios for fish fed different diets. The cost analysis indicated that it was profitable to use crocodile meat meal in the diets of all size groups of O. mossambicus.

Summary: This study investigated the acute toxicity of Zinc Nano Particles (ZnO NPs) and bulk ZnO on tilapia fish. The results showed that high concentrations of ZnO NPs, ZnO, and the mixed solution had significant effects on the hematological parameters and histological architecture of the fish. Therefore, the indiscriminate use of ZnO NPs and ZnO should be avoided to prevent the reduction of the tilapia fish population in natural water bodies.

Summary: The study found that supplementation with tetradecylthioacetic acid (TTA) can reduce body lipid levels in juvenile Chinook salmon, but does not decrease precocious maturation rates in male fish and shows no gender differences. Growth was slowed during TTA feeding period, but recovered after returning to a standard diet.

Summary: The study found that the age of natural-origin spring Chinook Salmon broodstock does not consistently affect the rate at which their hatchery-raised male progeny mature, with variability largely attributed to dam- and sire-specific effects. This suggests a heritable component to precocious maturation.

Summary: Seasonally breeding fishes commonly exhibit consecutive and skip repeat spawning, which are regulated by energetic status and impact fisheries management. This study on steelhead trout found that both energy balance at spawning and feeding after spawning determine the reproductive schedule, extending the critical period model of salmonid maturation into the first 10 weeks after spawning.
